The search for more exoplanets continues as astronomers look for a so-called "Goldilocks" planet which could be fit to be inhabited by the biochemical likes of us.

Update: NASA says it has found a "Super-Earth" some 600 light years away that is 2.4 times the size of Earth and is in a habitable zone with a presumed surface temperature of some 72 degrees.
